RADIATOR WITH REMOVABLE SECTIONS.

Application filed December 30,1920. Seria1No.e34',048.

T 0 all whom it may concern:

Be it known that I, ERNEST HEY, citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Radiators with Removable Sections, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings which form a part of this specification.

My invention relates to radiators and objects of my improvements are to provide an improved radiator for dissipating the heat of cooling water of internal combustion engines and one which may be easily repaired by removing and replacing a part.

I accomplish these objects in the apparatus illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a radiator embodying my invention.

Fig. 2 is a cross-section thereof on the line II--II of Fig. l, the parts being disassembled to illustrate the construction.

Fig. 8 is a perspective view on a larger scale of some of the constituent parts of the apparatus shown .in Fig. 1.

Fig. 4 is a detailed sectional view of part of the assembled radiator, a section being taken in the plane indicated by the line.

IV-IV-IV, Fig. 3.

Fig. 5 is a detailed section in the plane indicated by the line V-V, Fig. 2.

Fig. 6 is a separate view of one element of the core, or coolingsurface.

Fig. is a detailed sectional view showing the method'of attaching the water tube to the crown sheet or plane end surface of the cooling elements.

Fig. 8 is a plan view of a part of said sheet showing two cooling tubes.

Fig. 9 shows a modified construction of the cooling element.

Figs. 10 and 11 are respectively sectional elevations of a passage in another form of cooling element and a plan of said element and a part of the adjacent crown sheet.

Fig 12 is a modified form of construction of an element of the cooling surface.

a indicates the radiator as a whole, having the lower reservoir 6 and the upper reservoir 0 with the core 03 d interposed between the two reservoirs and consisting of a plurality of elements 6 6 Each of these elements consists of crown sheets 6 e oneat eachyend, with water passages extending between and through said sheets, with means for dissipating the heat between said; crown sheets. The adjacent crown sheets 6 c of adjacent elements are provided with tengues' and grooves forming a dowel construction as illustrated in Fig. 3. fsindicatesfa:holding strip of metal having the parts or strips f extending'parallel to each other and transversely of the radiatoifi'andthe part f j'extending along the back of the radiator. A holding strip 7 'is; secured to the lower surface of the upper reservoir 0 and to the upper surface of the lower reservoir 7) by bolts passing through the holes 7 'in the part f of said" holding strip. The ends of the parallel aparts or-strips 7" which are reare provided withv mote from the partf bolt holes f.

There is a soft metal -washer g lying against the under surface of the reservoir 0 and the upper surface of the lower reservoir 2 between the holding strips f'and said sur ace. I The crown sheet or end plates 6 of each of the sections of the cooling surface eX- tends beyond the cooling tubes and fins to present projecting portions. These projecting portions of said plates engage over the strips 7 at thetopand under saidstrips "at thebottom.

The ends of the strips f extend beyond the cooling surface proper and engage under the forwardly projectingpa'rt of the end plates of the cooling section.- 6 indicates filling strips between the ends of the strips, f on the surface of. the endplates e at the top and the upper surface at the bottom.

h h are metal securing strips one of'which extends across the front of the radiator under the projecting portions of the top plates of the elements and is provided with bolt holes 7L through which bolts are passed to secure the parts together thus binding the whole to the reservoir 0 and clamping the to plates c and the ends of the strips 7" between said plate and the reservoir 0. The construction is the same at the lower end of the reservoir.

In Figs. 1, 2 and 3 I have illustrated the usual tube and fin form of cooling surface such as shown separately in Fig. 6. These tubes may be turned over the crown sheet or end plates e and beaded atthei edges as indicated at j and j in Figs. 7 and 8.

In Fig. 9 I have illustrated a zig-zag water passage which when a number are assembled to constitute the element, form diamond-shaped passages at the end. are plates which form girders, braces, or strengthening pieces in conjunction with the water passages ea. These pass preferably by and are secured to the upper and lower corners of the diamond shaped: figure formed by the united passages. In Ifi'g. 12 I have shown substantially the; same construction except that instead of the vertical plates @66 I have substituted flat plates to form the side of the diamond. figure as indicates ea; v

In Figs. 1 0 and 11 I have shown another form of'tube or water passage having al ternateenlargements and. contractions and this is supplemented bystraight binding plates j 7"; Y

The strengthening plates 666 ca and 7' not only perform their function as a strengthening means to form a rigid element but they also form surfaces which'absorb the radiant heat from the tubes having the water and dissipate thesame to the air passing through the radiatoii 1 If one of the sections becomes injured' the bolts passing. through the; Stripsfh' may be removed and the strips taken off and the section drawn out in front of-theradiator and a similar section inserted and thewhole bound together as before.

Claims:

1. In anapparatus of the kind described, the combination of a reservoir having a flat inner surface, a core consisting of a plurality of separate constituent seotionsieach of said; sections having anend plate -;proj eeting laterally therefrom, said end; plate; being adapted to engage. against said surface of said reservoir, and. flatstrips;engaging over the projecting portion ofsaid end plates and binding. them. tothe (inner surface-v of said reservoir.

2. In an apparatnsof the kindrdeseribed, the combination of a resenvoirhaving a flat inner surface, a core consisting of a plurality of separate constituent sections, each of said sections having anend plate adapted tov engage against said surface of said reservoir, means for locking adjacent end plates together, and means for securing said end plates to said reservoir to form a tight joint between said end plates and said reservoir, said end plates when in position having their separating lines running transversely of the radiator, a plate 7 having strips f extending therefrom, said plate being adapted to extend with its part longitudinally of the radiator along one edge of said radiator, the. strips 7' extending over the transverse dividin lines between said end plates, and means for securing said reservoir and end plates together to form a tight joint, substantially as and forthe purpose described.
